GENUS AND SPECIES

Anthurium andreanum L.

VARIETY DENOMINATION

‘ANTHDOSDOH’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium,botanically known as Anthurium andreanum L., and hereinafter referred toby the variety name ‘ANTHDOSDOH’. The new variety originated from ahybridization made in September 2006 in Bleiswijk, The Netherlands. Thefemale parent is a light pink Anthurium pot plant designated ‘9941-01’(unpatented), and the male parent was a pink Anthurium plant designated‘9741-04’ (unpatented).

A single plant was selected in June 2008 and has been asexuallyreproduced repeatedly by tissue culture in Bleiswijk, The Netherlandsover a seven-year period. The present invention has been found to retainits distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in theEuropean Union on Nov. 19, 2012, in Japan on May 26, 2014 and in Vietnamon Nov. 26, 2014. ‘ANTHDOSDOH’ has not been made publicly available orsold anywhere in the world more than one year prior to the filing ofthis application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Bleiswijk, The Netherlands:

-   -   1) Pink, lanceolate spathe;    -   2) Purple spadix with red tip;    -   3) Lanceolate leaf;    -   4) Extremely compact plant habit; and    -   5) Light green foliage.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographswhich show the overall plant habit including blooms and foliage of theplant; the colors shown are as true as can be reasonably obtained byconventional photographic procedures. The photographs are of a 50-weekold plant grown in a greenhouse in Bleiswijk, The Netherlands in April2015.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘ANTHDOSDOH’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 50-week oldplants which were planted from tissue culture in 12-centimeter pots andgrown in a glass greenhouse between 19° C. and 24° C. Observations weremade in April 2015. Color readings were taken under 5000 lux naturallight in the greenhouse. Color references are primarily to The R.H.S.Colour Chart of The Royal Horticultural Society of London (R.H.S.)(2001).

More blossoms            appear after some additional weeks so that a full flowering            and commercial plant will have 7 to 10 pink spathes. Smaller            blossoms may occur on less mature plants.-   Spadix:    -   -   Size.—Length: 1.5 cm to 2.5 cm (depending on flower size)            Width (at apex): 0.35 cm to 0.45 cm Width (at base): 0.4 cm            to 0.5 cm.        -   Shape.—Columnar.        -   Angle from spadix tip to peduncle.—160 to 180 degrees            (spadix is almost in one line with the peduncle).        -   Texture.—When the spathe is unfurling the spadix is smooth.            When the spadix matures, small stigmata protrude. The            stigmata are evenly distributed round the spadix. The spadix            matures from base to top, slowly giving the spadix a            somewhat rough appearance.        -   Color.—Immature: RHS 47A Mature: RHS 61A.-   Flowers:    -   -   Quantity per spadix.—90 to 110.        -   Spadix flower arrangement.—Bisexual, rounded in            cross-section.        -   Shape.—Rounded.        -   Size.—Length: 0.05 cm to 0.1 cm Diameter (maximum): 0.1 cm.        -   Color.—RHS 61A.-   Reproductive organs:    -   -   Stamens.—Not visible.        -   Pollen amount.—Very few.        -   Pollen color.—RHS 156D.        -   Pistil.—Quantity: Many Length: Less than 0.01 cm Color: RHS            61C.        -   Style.—Not observed.        -   Stigma.—Shape: Ovoid Diameter: Less than 0.01 cm Color: RHS            61C.        -   Ovary.—Rarely visible.        -   Ovary color.—Not measured.-   Fruit and seed set: None observed

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHDOSDOH’ differs from the female parent plant ‘9941-01’ (unpatented)in that ‘ANTHDOSDOH’ has a pink spathe, whereas ‘9941-01’ has a lightpink spathe.

‘ANTHDOSDOH’ differs from male parent plant ‘9741-04’ (unpatented) inthat ‘ANTHDOSDOH’ has a lanceolate spathe, whereas ‘9741-04’ has anovate spathe.

‘ANTHDOSDOH’ differs from commercial variety ‘ANTHUCOEN’ (U.S. PlantPat. No. 22,630) in that ‘ANTHDOSDOH’ has a small, lanceolate spathe,whereas ‘ANTHUCOEN’ has a larger, more ovate spathe. Additionally,‘ANTHDOSDOH’ has lanceolate leaves, whereas ‘ANTHUCOEN’ has cordateleaves.

‘ANTHDOSDOH’ differs from commercial variety ‘ANTHEBENEX’ (unpatented)in that ‘ANTHDOSDOH’ has a pink spathe, whereas ‘ANTHEBENEX’ has apurple spathe. Additionally, ‘ANTHDOSDOH’ has small, lanceolate leaves,whereas ‘ANTHEBENEX’ has larger, long ovate leaves.

I claim:
 1. A new and distinct variety of Anthurium plant named‘ANTHDOSDOH’, substantially as illustrated and described herein.
